Leg tube sliding locking mechanism for opening and closing folding tent

Abstract

A leg tube sliding locking mechanism for opening and closing a folding tent includes a sliding support sleeved on a leg tube, a jump bead, and a V-shaped spring. One end of the V-shaped spring is connected to the jump bead, and the other end of the V-shaped spring is fixed to an inner wall of the leg tube. A bushing is installed on an inner wall of the sliding support in a fitted manner.An upper end of the busing extends downward to form a pressing sheet, and the pressing sheet has a lower end extending outwards to a lower end of the sliding support. The pressing sheet covers the jump bead.
